Title: Tubular welding electrode - with longitudinal outer notches
IPC: B23K35/02
Filed: 1972-06-14
Abstract: Electrode consisting of a thin metal tube the bore of which is filled with a filler, has lengthwise outer continuous notches in the non-ferrous Ni- or Cu base tube, which are filled with a coating material.

Title: Plastic extrusion cooling bath system - using two coolers, one inside the other
Inventor: DITTRICH JOACHIM DIPL ING
IPC: B29C48/05
Filed: 1972-11-25

Title: Otto-cycle engine carburettor - delivers finely-vapourised mixture only when idling or at low speeds
Inventor: BRAND HEINRICH
IPC: F02M3/08

Title: Mounting assembly for small motor laminated rotor core - has pins driven into holes deforming rotor to clamp smooth shaft
Inventor: GERMER ARMIN
IPC: H02K1/28
Filed: 1973-10-02
Abstract: The mounting assembly for mounting a small motor laminated rotor core onto its smooth shaft has three regularly spaced holes set into the rotor core parallel to the latter axis and close to the region that touches the smooth shaft. The holes may have various shapes and are located as close to the smooth shaft surface as practicable.

Title: Hollow metal profile for supporting of panels - has side grooves for engaging with attachment clamps
Inventor: HERZBERG KARL
IPC: E01F9/623
Filed: 1974-02-13
Abstract: The posts made from hollow metal profiles are used for supporting flat panels, for example, road signs. They are preferably extruded from an aluminium and magnesium alloy.
